DESIGN SUPPORT SYSTEM FOR SEMICONDUCTOR INTEGRATED CIRCUIT, DESIGN METHOD FOR SEMICONDUCTOR INTEGRATED CIRCUIT, DESIGN SUPPORT PROGRAM FOR SEMICONDUCTOR INTEGRATED CIRCUIT, AND MANUFACTURING METHOD OF SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PPROBLEM TO BE SOLVED: To provide a design support system for a semiconductor integrated circuit, a design method for the semiconductor integrated circuit, a design support program for the semiconductor integrated circuit, and a manufacturing method for the semiconductor integrated circuit, capable of raising a replacement rate from a single cut via to multi-cut bear and improving the reliability and manufacturing yield of the semiconductor integrated circuit. PSOLUTION: The design support system is provided with: a global routing means 13 for allotting a global routing path 22 to a routing area, estimating the number of via generation of the global routing path 22, calculating routing resource consumption information needed to connect the global routing path 22 with the multi-cut via, and referring to routing congestion to be calculated each of a plurality of rectangle areas to optimize a global routing path while aiming to uniform the routing congestion according to multi-cut via routing; a detailed routing means 14 for reading the global routing result and routing a detailed routing in the routing area by using the routing resource consumption information; and a multi-cut via replacement means 15 for reading the detailed routing result to replace a via for connecting the routing areas with the multi-cut via.
